Constructor & Destructor Documentation

◆ __construct()

assOrderingQuestion::__construct (   $title = "",
  $comment = "",
  $author = "",
  $owner = -1,
  $question = "",
  $ordering_type = OQ_TERMS 
)

assOrderingQuestion constructor

The constructor takes possible arguments an creates an instance of the assOrderingQuestion object.

Parameters
string$titleA title string to describe the question
string$commentA comment string to describe the question
string$authorA string containing the name of the questions author
integer$ownerA numerical ID to identify the owner/creator
string$questionThe question string of the ordering test
int$ordering_type

Member Function Documentation

◆ addAnswer()

assOrderingQuestion::addAnswer (   $answertext = "",
  $solution_order = -1,
  $depth = 0 
)

Adds an answer for an ordering choice question.

The students have to fill in an order for the answer. The answer is an ASS_AnswerOrdering object that will be created and assigned to the array $this->answers.

Parameters
string$answertextThe answer text
double$pointsThe points for selecting the answer (even negative points can be used)
integer$orderA possible display order of the answer
integer$solution_orderAn unique integer value representing the correct order of that answer in the solution of a question
integer$depthrepresents the depth of that answer @access public
